Redefining the literal string associated to the YYerror symbol

Hello,

in Bison 3.6 is it possible to redefine the literal string associated to
the YYerror symbol (and to the YYEOF, YYUNDEF ones, although I don't
have immediate need for this)?

Doing it in the naive way:

%token YYerror "ERROR"

results in a warning:

warning: symbol YYerror given more than one literal string [-Wother]
  180 | %token YYerror "ERROR"
      |                ^~~~~~~

and in the literal string not being updated.

Thank you.

Cheers,
Dan
